[0001] [Cross - reference to Related Applications] This disclosure is based on Chinese Patent Application CN202210763495.8, entitled "Method for Measuring Common Signal of Terminal, Terminal and Storage Medium", filed on June 30, 2022. The priority of the said patent application is claimed, and all the disclosed content is incorporated herein by reference in its entirety.

[0002] [Technical Field] This disclosure relates to the field of communication technologies, and particularly to a method for measuring common signals of a terminal, a terminal, and a storage medium.

Background Art

[0003] With the deployment and wide application of 5G systems, in order to better meet certain needs such as reducing the complexity and cost of devices, decreasing dimensions, and consuming less energy from terminal IoT applications such as industrial wireless sensors, video surveillance, and wearable devices, Redcap (Reduced Capability) terminals have emerged. For each Redcap terminal within a service cell, when each of the Redcap terminals needs to measure common signals and common channels, all of them need to switch from a small - bandwidth dedicated BWP (Bandwidth Part) to a BWP including CD - SSB (Cell Defining - Synchronization Signal Block), and temporarily move the corresponding services to the BWP including CD - SSB. After the measurement is completed, they switch back to the small - bandwidth dedicated BWP again. In this way, problems such as frequent switching of BWP occur, the power consumption of Redcap terminals is large, services are easily interrupted temporarily, and there is also a possibility of causing congestion in the BWP including CD - SSB.

Obviously, the drawings described below are some embodiments of the present disclosure, and those skilled in the art can also obtain other drawings based on these drawings without creative efforts.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, with reference to the drawings in the embodiments of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0011] The flowcharts shown in the drawings are merely illustrative and do not necessarily include all contents and operations / steps, nor are they executed in the described order. For example, an operation / step may be decomposed, combined, or a part of it may be merged, so the actual execution order may be changed according to the actual situation.

[0012] It should be understood that the terms used in the specification of the present disclosure are only for describing specific embodiments and are not intended to limit the present disclosure. For example, as used in the specification and claims of the present disclosure, unless clearly indicated otherwise in the context, the singular forms "one", "a", and "the" are intended to include the plural forms.

[0013] The deployment of 5G systems is progressing and their applications are expanding. To better meet the specified needs such as reducing the complexity and cost of devices, decreasing dimensions, and consuming less energy from terminal IoT applications such as industrial wireless sensors, video surveillance, and wearable devices, Redcap (Reduced Capability) terminals have emerged. For each Redcap terminal within a service cell, if each of these Redcap terminals needs to measure common signals and common channels, they all need to switch from a dedicated BWP (Bandwidth Part) with a small bandwidth to a BWP that includes CD-SSB (Cell Defining-Synchronization Signal Block), and temporarily move the corresponding services to the BWP that includes CD-SSB. After the measurement is completed, they switch back to the dedicated BWP with a small bandwidth. In this way, problems occur where the BWP is frequently switched, the power consumption of Redcap terminals is high, services are easily interrupted temporarily, and it may also cause congestion in the BWP that includes CD-SSB.

[0014] For example, as shown in FIGS. 1 and 2, only two Redcap terminals, namely Redcap UE (User Equipment) 1 and Redcap UE2, are taken as examples. In FIG. 1, at time T1, terminal 1 (Redcap UE1) is switched from the small-bandwidth bandwidth 1 (BWP1) to the bandwidth 0 (BWP0) that includes the cell-defining period signal block (CD-SSB) for measurement, obtains information such as the corresponding signal strength, and terminal 2 (Redcap UE2) is switched from the small-bandwidth bandwidth 2 (BWP2) to the bandwidth 0 (BWP0) that includes CD-SSB for measurement, and obtains information such as the corresponding signal strength. After the measurement is completed, as shown in FIG. 2, at time T2, terminal 1 (Redcap UE1) is switched from bandwidth 0 (BWP0) to the small-bandwidth bandwidth 1 (BWP1), and terminal 2 (Redcap UE2) is switched from bandwidth 0 (BWP0) to the small-bandwidth bandwidth 2 (BWP2).

[0015] Thus, there is a problem of frequently switching the BWP, which easily causes temporary interruption of services and congestion of BWP0.

[0016] To solve the above problems, embodiments of the present disclosure provide a method for measuring a common signal of a terminal, a terminal, and a storage medium, so as to solve the problem that frequent switching of the BWP results in high power consumption of the terminal, easy temporary interruption of services, and possible congestion of the BWP including CD-SSB.

[0017] Hereinafter, some embodiments of the present disclosure will be described in detail with reference to the drawings. Unless there is a contradiction, the following embodiments and features in the embodiments can be combined with each other.

[0018] Referring to FIG. 3, FIG. 3 is a flowchart of a method for measuring a common signal of a terminal according to an embodiment of the present disclosure.

[0019] As shown in FIG. 3, the method for measuring the common signal of the terminal may include step S101 and S102, or step S101 and S103, or steps S101 to S103.

[0020] S101: Determine whether the terminal is a master terminal in the terminal cluster to which the current terminal belongs. If so, execute step S102; otherwise, execute step S103.

[0021] S102: Switch to a carrier bandwidth including common broadcast information to measure a common signal, obtain first common signal data, and transmit the first common signal data to a sub-terminal in the terminal cluster.

[0022] S103: Obtain first common signal data measured by the master terminal, and obtain second common signal data corresponding to the current terminal based on the first common signal data.

[0023] Here, the terminals include but are not limited to Redcap terminals. Exemplarily, all terminals in each terminal cluster are located in the same serving cell. Based on the serving cell corresponding to each terminal, each terminal is classified into a cluster, and it is determined that each terminal located in the same serving cell belongs to the same terminal cluster.

[0024] For example, assume there are four terminals connected to the same local area network. The terminal IDs of the four terminals are Terminal 1, Terminal 2, Terminal 3, and Terminal 4 respectively. These four terminals are located in two serving cells, and the cell IDs of the two serving cells are Cell 1 and Cell 2 respectively. Here, Terminal 1, Terminal 2, and Terminal 3 are located in Cell 1, and Terminal 4 is located in Cell 2. Then, Terminal 1, Terminal 2, and Terminal 3 belong to one terminal cluster, and Terminal 4 belongs to another terminal cluster.

[0025] During the normal operation process, in the same terminal cluster, only one terminal is used as the master terminal at the same time, and all other terminals are sub-terminals. The determination of the master terminal may be realized in various ways such as adopting rotation or applying for arbitration, and the present disclosure does not specifically limit it.

[0026] It should be noted that the method for measuring the common signal may be operated on the master terminal or on the sub-terminal. In one exemplary embodiment, when it is known that the current terminal itself is the master terminal, the method for measuring the common signal of the terminal, when it is necessary to measure the common signal, includes the steps of switching the master terminal to a carrier bandwidth including common broadcast information to measure the common signal, obtaining first common signal data, and transmitting the first common signal data to the sub-terminals in the terminal cluster. In another exemplary embodiment, when it is known that the current terminal itself is a sub-terminal, the method for measuring the common signal of the terminal may further include the step of obtaining first common signal data measured by the master terminal and obtaining second common signal data corresponding to the current terminal based on the first common signal data.

[0027] In one exemplary embodiment, before each terminal in the terminal cluster measures the common signal, an offset calibration operation of each terminal's information may be first performed to obtain calibration offset information between each terminal in the terminal cluster and each other terminal. Exemplarily, the calibration offset information includes, but is not limited to, a signal strength calibration difference value.

[0028] In some embodiments, before the step of determining whether the current terminal is a master terminal in the terminal cluster to which the current terminal belongs, the current terminal is switched to a carrier bandwidth including common broadcast information to measure a common signal, first calibration common signal data is obtained, and the first calibration common signal data is transmitted to each other terminal in the terminal cluster; receiving second calibration common signal data transmitted from each other terminal in the terminal cluster; and obtaining calibration offset information between the current terminal and each other terminal in the terminal cluster based on the first calibration common signal data and each of the second calibration common signal data.

[0029] Exemplarily, the carrier bandwidth including common broadcast information may be, but is not limited to, a BWP including CD-SSB. Hereinafter, taking the carrier bandwidth including common broadcast information as a BWP including CD-SSB as an example, the method for measuring the common signal of the terminal in the present disclosure will be described.

[0030] For example, still taking the terminals 1, 2, 3, and 4 listed above as examples, each terminal is switched to a BWP including CD-SSB for the first time to measure the common signal. According to the situation of each measurement, terminals with the same corresponding cell identification (cell ID) measured are determined as one terminal cluster. For example, terminals 1, 2, and 3 are one terminal cluster. Each terminal acquires the first calibration common signal data measured by itself, and transmits the first calibration common signal data measured by itself to each other terminal in the terminal cluster, and receives the second calibration common signal data transmitted from each other terminal. Here, the calibration common signal data corresponding to each terminal includes, but is not limited to, the common signal strength value, common channel PDU (Protocol Data Unit) information, etc. In this way, by determining the difference between the first calibration common signal data and each second calibration common signal data, the calibration deviation information between each terminal and each other terminal in the terminal cluster is obtained, and the calibration deviation information between each terminal itself and each other terminal in the terminal cluster is stored.

[0031] For example, still taking the terminals 1, 2, 3, and 4 listed above as examples, the basic measurement situation information after each of the four terminals is switched to a BWP including CD-SSB for the first time to measure the common signal is shown in Table 1.

[0032]

Table 1

[0033] Since the distances between each terminal and the base station are not the same and are changing, it is necessary to create a calibration difference value for the signal strength. On the other hand, for all terminals in the same cell, that is, each terminal in the same terminal cluster, the common channel PDU information is the same, and there is no need to create a calibration difference value.

[0034] In some embodiments, after the step of obtaining the calibration deviation information between the current terminal and each other terminal in the terminal cluster, a step of generating a calibration table for the current terminal based on the calibration deviation information between the current terminal and each other terminal in the terminal cluster and the terminal identification information of each other terminal is included.

[0035] Here, the terminal identification information includes, but is not limited to, a terminal ID, a terminal IP address, etc. In the calibration table, the calibration deviation information with other terminals and the terminal identification information of other terminals are associated one-to-one. For example, the signal strength calibration difference value and the terminal identification information are associated one-to-one.

[0036] For example, still taking Table 1 above as an example, based on the signal strength values of Terminal 1, Terminal 2, and Terminal 3, the calibration deviation information is calculated, and the generated calibration table for Terminal 1 is shown in the drawing.

[0037]

Table 2

[0038] Based on the signal strength values of Terminal 2 and Terminals 1 and 3, the calibration deviation information is calculated, and the generated calibration table for Terminal 2 is shown in Table 3.

[0039]

Table 3

[0040] Based on the signal strength values of Terminal 3 and Terminals 1 and 2, the calibration deviation information is calculated, and the generated calibration table for Terminal 3 is shown in Table 4.

[0041]

Table 4

[0042] Since the terminal 4 is in the coverage area of another cell and there is no other paired terminal, it is not classified into a terminal cluster, and the calibration table of the terminal 4 is empty.

[0043] When each terminal in the terminal cluster needs to measure a common signal, the master terminal and the slave terminal have different methods for measuring the common signal.

[0044] For example, still taking the terminal cluster including the terminals 1, 2, and 3 listed above as an example, when the terminal 1 is the master terminal at this time, the terminals 2 and 3 are slave terminals.

[0045] When a certain terminal among them needs to measure a common signal, first, in the terminal cluster to which the terminal belongs, it is determined whether it is currently the master terminal. If the current terminal is the master terminal, it switches to the BWP including CD-SSB for measurement to obtain the first common signal data of the master terminal. Then, the master terminal transmits the first common signal data to each slave terminal in the terminal cluster one by one.

[0046] Exemplarily, each terminal in the terminal cluster establishes a connection with a third party by means such as wired or Bluetooth (registered trademark), and the master terminal transmits the first common signal data to each other slave terminal in the terminal cluster by connecting to the third party of other terminals in the terminal cluster.

[0047] If the current terminal is a slave terminal, the slave terminal obtains the second common signal data corresponding to the slave terminal based on the first common signal data of the obtained master terminal and the first common signal data.

[0048] Exemplarily, the common signal data corresponding to each terminal in the terminal cluster includes common measurement information and common data information. Here, the common measurement information includes, but is not limited to, the common signal strength value, and the common data information includes, but is not limited to, the common channel PDU information, etc.

[0049] For example, taking the terminal 1 as an example, in this case, the terminal 1 is the master terminal. When the master terminal receives a request to measure a common channel / common signal from a certain sub-terminal, or when in this case, the master terminal itself has a need to measure a common channel / common signal, it switches to a BWP including CD-SSB for measurement. If the measured common signal strength value is -80 and the common channel PDU information is 11 22 33, then the common signal strength value and the common channel PDU information are transmitted one by one to each sub-terminal in the terminal cluster, that is, transmitted to the terminal 2 and the terminal 3.

[0050] In some embodiments, based on the first common signal data, the step of obtaining the second common signal data corresponding to the current terminal includes: differentiating and calculating the first common measurement information in the first common signal data to obtain the second common measurement information in the second common signal data; and determining the first common data information in the first common signal data as the second common data information in the second common signal data.

[0051] Exemplarily, the common signal strength value of the master terminal is differentiated and calculated to obtain the common signal strength value corresponding to the sub-terminal, and the common channel PDU information of the master terminal is directly determined as the common channel PDU information corresponding to the sub-terminal.

[0052] For example, differential calculation is performed on the fact that the common signal strength value corresponding to the terminal 1 is -80 to obtain the common signal strength value corresponding to the terminal 2, and the common channel PDU information 11 22 33 corresponding to the terminal 1 is determined as the common channel PDU information corresponding to the terminal 2.

[0053] In some embodiments, the step of differentiating and calculating the first common measurement information in the first common signal data and obtaining the second common measurement information in the second common signal data includes the step of obtaining calibration deviation information between the current terminal and the master terminal, and the step of adding the calibration deviation information to the first common measurement information to obtain the second common measurement information.

[0054] Exemplarily, based on the signal strength calibration difference value between the current terminal and the master terminal, the signal strength calibration difference value is added to the common signal strength value of the master terminal to obtain the common signal strength value of the current terminal.

[0055] In some embodiments, the step of obtaining the calibration deviation information between the current terminal and the master terminal includes the step of querying the calibration table of the current terminal to obtain the calibration deviation information between the current terminal and the master terminal, where the calibration table includes the calibration deviation information between the current terminal and each other terminal in the terminal cluster.

[0056] Exemplarily, based on the generated calibration table of each terminal, the calibration table corresponding to the current terminal is queried to obtain the signal strength calibration difference value between the current terminal and the master terminal.

[0057] In some embodiments, the step of querying the calibration table of the current terminal to obtain the calibration deviation information between the current terminal and the master terminal includes the step of determining the terminal identification information of the master terminal, and the step of querying the calibration table based on the terminal identification information and determining the calibration deviation information associated with the terminal identification information in the calibration table as the calibration deviation information between the current terminal and the master terminal.

[0058] In the calibration table of each terminal, the calibration deviation information between the terminal itself and other terminals and the terminal identification information of other terminals are associated one-to-one. By determining the terminal identification information of the master terminal and querying the calibration table, the calibration deviation information associated with the terminal identification information can be obtained, and the associated calibration deviation information is the calibration deviation information between the current terminal and the master terminal.

[0059] For example, terminal 2 is a sub-terminal. Terminal 2 receives and obtains that the signal strength value measured by terminal 1 (master terminal) is -80, queries the calibration table of terminal 2, and obtains that the signal strength calibration difference value between terminal 2 and terminal 1 is -10. Then terminal 2 calculates that the signal strength value at its location is -90, and decodes and stores the latest common channel PDU information 11 22 33.

[0060] Terminal 3 is also a sub-terminal. Terminal 3 receives and obtains that the signal strength value measured by terminal 1 (master terminal) is -80, queries the calibration table of terminal 3, and obtains that the signal strength calibration difference value between terminal 3 and terminal 1 is -15. Then terminal 3 calculates that the signal strength value at its location is -95, and decodes and stores the latest common channel PDU information 11 22 33.

[0061] In this way, a sharing process of common signal data is completed, and the operations of terminals 2 and 3 to switch the BWP are avoided.

[0062] As shown in FIG. 4, the measurement flow of the terminal is as follows. Step1: Determine whether the current terminal is the master terminal in the terminal cluster. If so, jump to Step2; otherwise, jump to Step5.

[0063] Step 2: Switch to the BWP containing CD-SSB and perform measurements and readings. Step 3: Transmit the measurement results to other terminals in the terminal cluster.

[0064] Step 4: When the measurement is completed, switch back to the original BWP. Step 5: Obtain the measurement results of the master terminal.

[0065] Step 6: Based on the measurement results of the master terminal, associate the calibration deviation information to obtain the measurement results of the current terminal.

[0066] Step 7: The measurement is completed. In this way, for each sub-terminal in the terminal cluster, each sub-terminal is prevented from frequently performing the operation of switching the BWP, reducing the power consumption of the terminal and the interruption time of the service, and avoiding the congestion of the BWP containing CD-SSB.

[0067] In the above embodiment, it is determined whether the current terminal is a master terminal in the terminal cluster to which the current terminal belongs. When the current terminal is a sub-terminal, the first common signal data measured by the master terminal in the terminal cluster is obtained, and based on the first common signal data, the second common signal data corresponding to the current terminal is obtained. Therefore, for the sub-terminals in the terminal cluster, measurements can be performed without switching to the carrier bandwidth containing common broadcast information, thereby preventing the terminal from frequently performing the operation of switching the carrier bandwidth, reducing the power consumption of the terminal and the interruption time of the service, and avoiding the congestion of the carrier bandwidth containing common broadcast information.

[0068] The embodiments of the present disclosure further provide a terminal. Referring to FIG. 5, FIG. 5 is a schematic block diagram of a terminal according to an embodiment of the present disclosure.

[0069] As shown in FIG. 5, the terminal 200 may include a processor 210 and a memory 220. Here, the processor 210 is connected to the memory 220 via a bus, and the bus is, for example, an I2C (Inter-integrated Circuit) bus.

[0070] Specifically, the processor 210 may be a microcontroller unit (MCU), a central processing unit (CPU), a digital signal processor (DSP), or the like.

[0071] Specifically, the memory 220 may be a Flash chip, a read-only memory (ROM), a magnetic disk, an optical disk, a USB memory, or a portable hard disk, etc. Various computer programs executed by the processor 210 are stored in the memory 220.

[0072] Here, when the processor 210 operates a computer program stored in the memory and executes the computer program, it is used to determine whether the current terminal is a master terminal in the terminal cluster to which the current terminal belongs, and when the current terminal is not a master terminal, to obtain first common signal data measured by the master terminal in the terminal cluster, and based on the first common signal data, to obtain second common signal data corresponding to the current terminal.

[0073] In some embodiments, after the processor 210 realizes the step of determining whether the current terminal is a master terminal in the terminal cluster to which the current terminal belongs, when the current terminal is a master terminal, it is used to switch to a carrier bandwidth including common broadcast information to measure a common signal, obtain the first common signal data, and transmit the first common signal data to slave terminals in the terminal cluster.

[0074] In some embodiments, the common signal data corresponding to each terminal in the terminal cluster includes common measurement information and common data information.

[0078] In some embodiments, the terminal identification information includes at least one of a terminal ID and a terminal IP address.

[0079] In some embodiments, before the processor 210 implements the step of determining whether the current terminal is a master terminal in the terminal cluster to which the current terminal belongs, the current terminal is switched to a carrier bandwidth including common broadcast information to measure a common signal, obtain first calibration common signal data, and transmit the first calibration common signal data to each of the other terminals in the terminal cluster; receive second calibration common signal data transmitted from each of the other terminals in the terminal cluster; and obtain calibration deviation information between the current terminal and each of the other terminals in the terminal cluster based on the first calibration common signal data and each of the second calibration common signal data.

[0080] In some embodiments, after the processor 210 implements the step of obtaining the calibration deviation information between the current terminal and each of the other terminals in the terminal cluster, it is used to implement the step of generating the calibration table of the current terminal based on the calibration deviation information between the current terminal and each of the other terminals in the terminal cluster and the terminal identification information of each of the other terminals.
